Watlow solid state power controllers complement the rapid
switching required by PID temperature controls and help deliver optimum system
performance and service life. Available in 1-phase and 3-phase/2-leg and 3-leg
configuration, Watlow power controllers meet most industrial heating
applications. Random, zero cross or phase angle fire options allow for a variety
of applications.

The DIN-A-MITE family is the ideal solid state replacement
for mercury displacement relays (MDRs) in an easy-to-install, compact,
touch-safe package. The solid state power controllers provides SCR control,
heatsink, wiring and touch-safe exterior in one package. By designing the
DIN-A-MITE as a total power controller unit, the need to prep wires for
terminals, locate the right heatsink and determine adequate terminations is
eliminated. It's a complete package you can install easily with CONTROL
CONFIDENCE®.

Four DIN-A-MITE styles meet most power controller needs with ratings from 18 to
100 amps with voltages from 24 to 600V~(ac). The four models match load
requirements with 1-phase, 3-phase/2-leg and 3-phase/3-leg switching. The
controllers also provide a convenient DIN-rail and sub-panel mount package.

Microprocessor-Based SCR Power Controller Designed for
Application Flexibility

For over thirty years Watlow® has been manufacturing solid
state power controllers. Watlow's new POWER SERIES represents the latest in SCR
power controller technology. This microprocessor-based product offers features
and application flexibility unmatched by any other SCR power controller on the
market today.

Capabilities include single-phase and three-phase models from
65 to 250 amps. Field configurable phase angle or zero-cross firing improves
application flexibility on site where you need it. 50/60Hz independent operation
means you can operate almost everywhere in the world without special calibration
considerations. Serial communications utilizing Modbus® protocol allow for
remote control setup, and monitoring of load status from a nearby computer
station or control room.

On-board semiconductor fusing improves reliability by
protecting the SCRs from heater short circuits. Plus, on-board heater bakeout
and control diagnostics can help eliminate initial start up problems. All this
in a touch-safe package that can be quickly and easily mounted in your control
cabinet.

Agency approvals ensure a product that meets world safety and
operational standards. You can be assured your power controller will be ideal
wherever you choose to do business.

CZR Solid State Contactors

The new SERIES CZR solid state contactor from Watlow®
provides a low-cost, highly compact and versatile solid state option for
controlling electric heat. With DIN-rail and back panel mounting standard on
every controllers, the CZR allows for simple and quick installation.

The extensive capabilities of the SERIES CZR include
single-phase, 24 to 50 amp zero-cross and random switching up to 600V~ (see
output rating curve). The unique integrated design removes the guesswork
associated with selecting a proper heat sink and precise terminations for the
application.

This controller holds many agency approvals and is ideal for
applications that require UL®, CSA and CE approvals. SERIES CZR contactors are
available in V (ac/dc) input contactor versions. All configurations are model
number dependent and factory selectable.
The SERIES CZR is reliably backed by a two-year warranty from Watlow.
